About Cometic
Cometic Gasket manufactures multi-layer steel head gaskets and complete gasket kits in Concord, Ohio. On a built V-twin running higher compression or a big-bore kit, the MLS head gasket is what keeps the top end sealed — which is why Cometic is the default spec on so many engine builds.
Regular maintenance often requires replacing primary cover gaskets, so having spares on hand is smart. This Cometic Twin Cam Inspection/Derby Cover Gasket 5-Pack provides reliable OEM-replacement seals for your Harley-Davidson Big Twin. Designed to prevent leaks, these gaskets ensure your primary stays sealed tight.
Why riders pick this
- 5-pack for multiple services or spares
- Direct OEM replacement gasket
- For Harley Big Twin Twin Cam engines
- Seals inspection and derby covers reliably
This Cometic Twin Cam inspection and derby cover gasket is sold in a convenient 5-pack, perfect for Harley-Davidson Big Twin owners who perform their own maintenance or for shops. These gaskets are engineered as direct OEM replacements, designed to seal the inspection cover without leaks or degradation over time. Having a multi-pack ensures you always have a fresh gasket on hand when opening up your primary.
Reliable Seals for Your Primary

Essential for Regular Maintenance
Every time you remove your inspection or derby cover, installing a new gasket is recommended to prevent leaks. This Cometic 5-pack makes it easy to follow best practices, ensuring your primary remains sealed and your ride stays clean. These gaskets are manufactured to OEM specifications and materials, providing confidence in their fit and long-term performance. Always verify your bike's original equipment part number (25416-99C) to confirm compatibility before purchasing.

Common questions
What size inspection cover does this 5-pack of gaskets fit?
These gaskets are designed to fit the Twin Cam inspection/derby cover on Harley Big Twin models. It's always a good idea to verify your cover diameter if your bike has been modified.
Why should I purchase a 5-pack instead of a single gasket?
A 5-pack is ideal for shops, owners of multiple bikes, or riders who want to have spare gaskets readily available. Gaskets should be replaced at every cover removal to ensure a proper seal.
Is this gasket the same quality as the OEM Harley-Davidson part?
Cometic manufactures this gasket to OEM specifications and materials, making it a direct replacement engineered for equivalent fit and performance to the original equipment part.
